Title: Apparatus for maintaining a predetermined relationship between the speeds of two independently driven members
Inventor: LEVETUS FRANCIS BENJAMIN
IPC: F16H61/40
Filed: 1954-09-06
Abstract: 790,626. Fluid-pressure servomotor-control systems. KEELAVITE CO., Ltd. Nov. 11, 1955 [Sept. 6, 1954], No. 25850/54. Class 135. An hydraulic motor A, Fig. 1, which is supplied with pressure liquid by a pump A<1>, is set for a given speed by either adjusting the constant-speed motor driving the pump or the pump capacity whilst metering pumps F<1> and H<1>, chain-driven from the motor A and a second motor B, respectively, and arranged in series so that the output of one just meets the input requirement of the other when the motors have the required speed relationship. The motor B is supplied with pressure liquid by a pump B<1> also driven by a constant speed motor; the capacity of the pump B is such as to enable the motor B to be driven at the required speed in relation to the motor A and to provide surplus liquid which escapes through a valve D to the reservoir C<1>. Any reduction in set speed of the motor B and hence pump H<1> brings about a pressure increase in the valve actuating chamber E<2> which causes the valve D to close and hence effects an increase in the speed of the motor B since pump H<1> is connected by a line G to pump F<1> and a line G<1> to the chamber E<2>; an increase in the speed of the motor B above that set causes valve E<2> to open and reduce the speed of the motor B. The range of speed relationship between the motors A and B and the sensitivity of each range can be varied by adjusting the relative capacities of the metering pumps F<1> and H<1>. The phase relationship between the motors A and B can be altered during operation of the apparatus by actuating a manual pump F4 to inject into or withdraw from the line G an appropriate quantity of liquid. An adjustable escape orifice G<2> may be provided in the line G as an alternative or additional means of varying the speed relationship between the motors. In a modification, the pump K, Fig. 2, supplies liquid to series-connected motors N and P, the capacity of the motor N being greater than that of the motor P whilst across the metering pump Q is a cylinder containing an adjustable spring-loaded piston T<1>, the adjustment of which forces liquid into or withdraws it from the line S connecting the pump Q to the other metering pump R to bring about a change in phase between the motors N and P. The valve D is arranged and operated as in Fig. 1. The pump F4, Fig. 1, and piston T<1> may be automatically operated and the pump F<4> may be of the variable capacity type. The valve closure part E and the pressure responsive part E<1> of the valve D need not be a unitary structure as shown. Specification 711,486 is referred to.

Abstract: 594,309. Generating combustion products under pressure. STRUB, R. Dec. 27, 1944, No. 25877. Convention date, Dec. 31, 1943. [Class 51 (i)] [Also in Group XXVI] A continuous combustion gas turbine plant of the kind in which the power gas is produced for the useful output turbine at a pressure which varies in accordance with the output has a regulating device for automatically adjusting the quantity of fuel admitted to the combustion chamber and a limiting device operated by the combustion chamber pressure for determining the range of adjustment of the fuel quantity. The permitted regulating range is greater at high combustion chamber pressure than at low. The regulating apparatus shown, Fig. 2, has a fuel valve 46 controlled by the temperature at the' outlet of an air heater contained in the combustion chamber 20 through a rod 45. The range of travel of the valve 46 is determined by the position of the slot 51 in the plate 52 and a pin 48 on the valve spindle 47. The position of the plate 52 is controlled by a spring-loaded piston 57 acting through a lever 59. The piston 57 is actuated by the pressure in the combustion chamber 20. The control can be adjusted to suit the air inlet temperature by means of the temperature transmitter 38 which acts through the lever system 61, 62, 63 and 64 to alter the position of the fulcrum 60 of the lever 59. For changes of load, the fuel valve 46 is operated by the hand regulator 34. The. spring 49 allows movement of the regulator 34 or rod 45 when the pin 48 abuts against the side of the slot 51.

Title: Coin boxes for vending machines
Inventor: DEAN ROBERT LONGUEVILLE
IPC: G07F9/06
Filed: 1961-07-21
Abstract: 1,023,234. Coin boxes for coin-freed apparatus. R. L. DEAN, and D. M. PRICE. July 20, 1962 [July 21, 1961], No. 26462/61. Heading G4V.  A coin box for an automatic vending machine comprises a pivotally mounted flap 14 having a slot 16 very slightly larger than the crosssection of a coin for which the box is intended, the flap being positioned so that when the box is upright the slot registers with one end of a shoot 11 through which coins enter the box, and when the box is inverted the flap swings about a pivot 15 under the force of gravity and the slot is moved out of register with the end of the shoot. The arrangement prevents the unauthorized removal of coins from the box when the box is removed from the machine for replacing with an empty box. The shoot 11 has a wide opening 10 at its upper end for receiving coins after the vending machine has been operated and at its lower end 13 is just large enough to pass a correct coin, the coin passing through the slot 16 in the flap and a slot 17 in an internal wall 18 of the box. The flap has a weight 21 which abuts a stop 19 in the upright position of the box. Where the box is inverted, gravity acts on the weight to move the flap about the pivot 15 and the slot 16 out of register with the lower end of the shoot and the slot 17. The lower end 22 of the box is hinged at 23 and a tongue is provided for a padlock. The shoot may be in the form of a part-cylindrical plate concentric with the curved end of the flap.

Title: Improvements in and relating to feed water regulators for steam generators
IPC: F22D5/10
Filed: 1928-09-15
Abstract: 323,208. Mumford, Ltd., A. G., and Tait, E. B. Sept. 15, 1928. Valves controlled by pilot or relay valves. - A boiler-feed regulator of the kind having a main valve actuated by fluid pressure under the control of a float-actuated auxiliary valve, is provided with a compound main valve, the smaller valve being arranged to open in advance of and close before the larger valve. In the form shown in the Figure, the smaller valve 6 seats on the larger valve 1 which is coupled by a tubular spindle 2 to a piston 3 having a tubular extension 8 working in a base 9 to provide an annular chamber 15. The smaller valve is coupled to a piston 7 working in the tubular spindle 2 and provided with an axial passage 20, the lower end of which may have a renewable seat and co-operates with a needle. valve 21 actuated directly or indirectly by a float controlled by the water level in the boiler. The spindle 2 is ported at 11 to permit feed water to act on the underside of valve 6 and the upper side of piston 7. Feed water passes to the underside of the piston 7 through an eccentric passage 12, and, when the needle valve is open, consequent on a high water level in the boiler, said feed water passes away through the axial passage 20 and transverse passage to an annular groove 19 always in communication with a passage 16, 16 leading to an annular chamber 17 in the piston 3 always in communication with a drain passage 18. As the water level falls, the needle valve approaches its seat, causing pressure to bank up beneath the piston 7, so moving the valve 6 towards its open position. If, after the valve 6 is fully open, the level continues to fall, the consequential further use of the.piston closes communication between the exhaust groove 19 and a passage 13 in the piston 3 leading to the chamber 15 and opens communication between passages 14 and 25 in the pistons 3, 7 respectively to connect the chamber 15 to the space below the piston 7 and so cause pressure to build up beneath the piston 3 and open the main valve. This movement continues until communication between the passages 14, 25 is interrupted. In a modification, the needle valve 21 is replaced by a needle valve, designed to give a finely graduated opening, arranged in a separate float box and connected by piping to the chamber beneath the piston 7.

Title: Machine for testing the accuracy of curves having helical characteristics and indicating or measuring errors therein
IPC: G01B5/16
Filed: 1945-10-11
Abstract: 610,331. Gauging-apparatus. FELLOWS GEAR SHAPER CO. Oct. 11, 1945, No. 26548. Convention date, March 2. [Class 106 (ii)] A machine for testing helical curves is characterised in that driving means includes a rotatable element adapted to cause and to synchronise rotation of the test-piece and linear displacement of a carriage carrying a dial gauge or the like, the feeler of which is in engagement with the surface of the test-piece. The test-piece 11 is rotatably mounted between head and tail stocks (not shown) and the measuring instrument 13, having a feeler 14 to engage a tooth of the test-piece, is adjustably mounted on a measuring carriage 12 which is supported on the main structure (not shown) for movement in a direction parallel to the axis of the test-piece. The carriage may be moved by means of a wheel 15 which rotates a shaft 16, an offset ratio bar 22 on the shaft engaging a pin 23 on the carriage. The extent of movement of the carriage for a given rotation of the shaft 16 may be set, according to the angle of the teeth on the test-piece, by adjusting the pin 23 vertically on the carriage by means of a screw and hand crank (not shown) and the pin is maintained in contact with the ratio bar by means of a weight 29 connected to the carriage. The shaft 16 also carries a second ratio bar 31 which engages a similarly adjustable pin 32 and so imparts vertical movement to a drive slide 33, the weight of which maintains the pin and arm in contact. The drive slide is secured, by means of clamps 45, 51, controlled by a knob 55, to either portion of a steel tape 34 and so imparts rotary movement to a disc 35 fast on a spindle carrying the test-piece. The tape is secured to the disc 35, and to an idler mounted on a spring-located arm 37, by means of studs. The test-piece is thus rotated as the measuring instrument is moved linearly so that the latter will indicate any variations from true form of the helical teeth of the testpiece. The feeler 14 may control recording means as described in U.S.A. Specification 2,305,264.
